Looks like one of my 3 tops I'm growing.. Doesn't look like smooth cayenne that's for sure.. It has major claws/saws if you get near it..
I think Pineapples are enjoyable to grow, and limited risk for a fruiting plant. I killed one when my heater broke, but the pup larger than the rotted one is doing just fine.. I have a crap-load of smooth cayenne pups to separate from one fruiting mother..
Another good thing about pineapple vs banana's when unknown..
Pineapples are limited in what it can be versus banana's.. Good thing most pineapples are edible.. :^)
